Introducing the Evolution PSV™

Evolution PSV Incorporates Air-Foam Floatation Technology For clients with high/moderate skin protection needs and moderate positioning needs Lightweight Easy to adjust

Components Air-Foam Floatation Cushion PSV Valve Modifiable Wedge Cover

Air-Foam Floatation Cushion

Air-Foam Floatation Technology All VARILITE products incorporate Air-Foam Floatation technology Air is throughout the open cell foam- no separate “air bladder” Air provides pressure distribution Foam provides postural support, maintains cushion shape Research has shown that Air-Foam Floatation technology is the best at minimizing vibration transmission

Evolution Foam Stiffness Postural support is created by the 3 types of foam: –Softest foam under the ischium –Medium foam under the thighs/femurs –Firmest foam for medial and lateral thigh support

Ischial Area Foam Reduces the surface interface pressure underneath IT’s and sacrum Softest foam for the decubitus- sensitive area of the IT’s

Ischial Area Foam Indent due to firmer foam pushing up more on cushion surface than the less firm ischial area The cushion has NOT taken a set or failed Cushion is functioning normally Reduces the surface interface pressure underneath IT’s and sacrum

Thigh Area Foam Firmer than ischial area foam Creates pre-ischial ridge and pelvic bucketing Maintains pelvic position by restricting forward and lateral pelvic migration Provides support during functional transfers

Medial & Lateral Support Foam Firmest foam area Medial & lateral thigh support minimizes lower extremity adduction & abduction Posterior & lateral pelvic support provides stability Postural support created through immersion

Four way stretch fabric The open cell foam block is bonded to fabric so the cushion holds air The four-way-stretch fabric provides maximum conformity during immersion for optimal pressure distribution Puncture & water resistant

PSV Valve

Eliminates guesswork Precise Reliable Easy PSV: Pressure Setting Valve

3 steps to adjust PSV 1.Cushion inflated, valve closed

3 steps to adjust PSV 1.Cushion inflated, valve closed 2.Set valve to indicator 1, 2 or 3 air will escape for seconds and then stop

Modifiable Wedge

The Role of The Modifiable Wedge Cut horizontally or vertically to achieve the desired wedge shape for maximum pressure reduction and positioning

The Role of The Modifiable Wedge Cut horizontally or vertically to achieve the desired wedge shape for maximum pressure reduction and positioning Cut down the middle for unilateral elevation

Cushion Cover

The Importance of a Good Cover Available in both mesh and incontinence Machine washable Non-skid surface on bottom Reticulated foam inside promotes air exchange and improves pressure distribution Always use the Evolution with its cover

Case Example #1 50 yr old male living in an assisted living facility Diagnosis: cerebral palsy with spastic muscle tone and fixed contractures at multiple joints including hips & knees Presents with “C” shaped posture (posterior pelvic asymmetry) History of sacral pressure ulcers Dependent for repositioning Complains of discomfort & sliding Currently using air-only skin protection wheelchair cushion

FRONT Current cushionEvolution Case Example #1

Case Example #2 42 yr old male living independently in home setting Fell 100’ 15 yrs ago sustained multiple injuries including T3 incomplete SCI Brown-Sequard syndrome with asymmetric spasticity History of a pressure ulcer at left trochanter with subsequent flap surgery
